OptioLaser S200 Laser Sensor

Principle of Operation

The OptioLaser S200 series offers an optional visible alignment laser, RS232 and 4-20mA outputs. It uses an infrared semiconductor, GaAs laser diode. A light energy wavelength of approximately 905 nanometers, with a beam divergence of 3 milliradians (equal to 3ft at 1000ft), travels to the material being measured.

Any solid or liquid target in its path, will reflect back a certain percentage of the emitted energy. The OptioLaser calculates the distance, based on the transit time the laser pulse travels to the material and back.
